Attention and Biases: Evidence from Tax-Inattentive Investors
Abstract
We first provide evidence of investor inattention to a very simple and well-known capital gains tax exemption in the Brazilian stock market. We then show that inattentive investors exhibit worse trading performance and stronger trading biases even after controlling for several investor-level variables, such as past trading experience. The evidence is consistent with inattention being one of the explanations for the prevalence of behavioral biases.
